Islet cell tumors of the pancreas: pathologic-imaging correlation among size, necrosis and cysts, calcification, malignant behavior, and functional status.

Multidetector CT imaging features of solid pseudopapillary tumours of the pancreas in male patients: distinctive imaging features with female patients

“…SPTs are known to exhibit slow and progressive contrast enhancement, whereas most of the neuroendocrine tumours exhibit early homogeneous and prolonged enhancement up to the delayed phase. 5,16 In our study, SPTs in male and female patients also showed progressive enhancement in the solid portion of the tumour (81.8% vs 79.0%). Several imaging features of SPTs differed from those of pancreatic adenocarcinoma.…”

Xanthogranulomatous Inflammation of the Peripancreatic Region Mimicking Pancreatic Cystic Neoplasm

“…As observed in the case presented here, pathologic condi- (6) (21). Also, acinar cell carcinoma and ordinary ductal adenocarcinoma rarely undergo cystic change (19,20 …”

Preoperative Tumor Studies Using MRI or CT in Patients with Clinically Suspected Insulinoma

“…The smaller tumors tend to be homogeneous lesions without local invasion or distant metastases and typically are insulinomas. Larger tumors more commonly demonstrate cystic changes, necrosis, calcification, local invasion, vascular invasion, and distant metastases, and they are either clinically silent lesions or are associated with less clinically evident endocrine syndromes than are insulinomas [12]. Insulinomas have a much more dramatic clinical manifestation than the other functioning islet cell tumors.…”
